Refactor Pt. 1 - Made the GameLevel superclass; Pulled out caughtShip() and pop(); aligned variable names
Refactor - Round 2
Refactor - Part 3; The old *Level.m files are now just shells for being called by the CCBI file until we figure out how to change that. All functionality condensed into GameLevel.m
